The Town number four was substituted with Shefki Kuqi replacing him in the closing stages of the match and Richard Naylor moving to central defence due to McGreal seeming to take a knock on his calf.
According to Town boss Joe Royle, the damage will be known more on Sunday: “We will have a look at him on Sunday but he is a doubt at the moment. The good thing is that he came off straight away.” he told the Official Club Website.
